Abstract
Provided is a reading apparatus that includes a light source that emits a light to a source material and an image pickup element that receives the light reflected by the source material, to thereby read the source material. The image pickup element is disposed so as to move to a plurality of positions at each of which the image pickup element is oriented at a different angle with respect to a surface to be read of the object to be read, and to perform reading at the plurality of positions. The reading apparatus compares read values obtained by the image pickup element at the plurality of positions to thereby decide a property of an image expressed on the object to be read.
Claims7
A reading apparatus comprising:
- a light source that emits a light to an object to be read;
- and
- an image pickup element that receives the light reflected by the object to be read, to thereby read the object to be read,
- wherein the image pickup element is disposed so as to move to a plurality of positions at each of which the image pickup element is oriented at a different angle with respect to a surface to be read of the object to be read, and to perform reading at the plurality of positions;
- wherein the reading apparatus further comprises a decision unit that compares read values obtained by the image pickup element at the plurality of positions to thereby decide a property of an image expressed on the object to be read.
A reading apparatus comprising:
- a light source that emits a light to an object to be read;
- and
- an image pickup element that receives the light reflected by the object to be read, to thereby read the object to be read,
- wherein the image pickup element is disposed so as to move to a plurality of positions at each of which the image pickup element is oriented at a different angle with respect to a surface to be read of the object to be read, and to perform reading at the plurality of positions, and
- wherein the reading apparatus is configured so as to execute prescanning and regular scanning of the object to be read, wherein the prescanning includes reading the object to be read with the image pickup element at one or more positions among the plurality of positions, to thereby decide whether to read the object to be read at all of the plurality of positions on the basis of a reading result obtained at the one or more positions;
- and the regular scanning includes reading the object to be read with the image pickup element at all of the plurality of positions in the case where it is decided to read the object to be read at all of the plurality of positions, and reading the object to be read with the image pickup element at one of the plurality of positions in the case where it is not decided to read the object to be read at all of the plurality of positions.
A reading method to be performed by a reading apparatus that includes a light source that emits a light to an object to be read and an image pickup element that receives the light reflected by the object to be read to thereby read the object to be read,
- the method comprising causing the image pickup element to move to a plurality of positions at each of which the image pickup element is oriented at a different angle with respect to a surface to be read of the object to be read, causing the image pickup element to read the object to be read at the plurality of positions, and comparing read values obtained by the image pickup element at the plurality of positions to thereby decide a property of an image expressed on the object to be read.
